Selaginellales

Description

Selaginellales, also known as spike mosses, are a group of vascular plants that are commonly found in tropical and subtropical regions. They are characterized by their small, scale-like leaves that grow in rows along the stem. The plants can be either creeping or upright in habit, and can range in size from just a few centimeters to over a meter in height.

Taxonomic Information

Appearance

Selaginellales are known for their unique appearance, which includes small, scale-like leaves that grow in rows along the stem. These leaves can be green or various shades of brown or bronze, and can have a glossy or matte finish. The plants can be either creeping or upright in habit, with some species producing large, cone-like structures that contain spores.

Care Guide

To care for Selaginellales, it is important to provide them with the right amount of water, fertilizer, and sunlight. They prefer well-draining soil that is kept evenly moist, but not waterlogged. Fertilizer should be applied sparingly, as too much can cause the plants to become leggy and weak. Selaginellales prefer bright, indirect sunlight and should be protected from direct sun, which can scorch their leaves. They are hardy in USDA zones 9 through 11.

Common Pests & Diseases

Selaginellales are relatively pest and disease-free, but they can be susceptible to mealybugs, spider mites, and scale insects. These pests can be controlled with insecticidal soap or neem oil. Overwatering can also lead to fungal diseases, such as root rot, which can be prevented by allowing the soil to dry out slightly between waterings.

Habitat

Selaginellales are found in a variety of habitats, including rainforests, savannas, and deserts. They can grow in both sunny and shady conditions, and are often found growing on rocks, trees, or other plants.
